Answer (if you're me, at least) is, you don't.
There. The barn cat. Haven't decided on a name yet, though Fractal is the leading entry. It's a happy little purrbox, for sure, the reason I picked it over some of the others which were much more skittish. It came out of the crate after an hour long drive and right away started purring and wandering around the New World.
So now we have two black dogs, one black chicken, and one black cat.
